Installation and Usage

View full documentation.

Download the latest release for direct use in the browser, or install via NPM:

npm install linkifyjs linkify-html

Quick Start

When developing in an environment with JavaScript module loader such as Webpack, use an import statement:

import * as linkify from 'linkifyjs';
import linkifyHtml from 'linkify-html';

Or in Node.js with CommonJS modules

const linkify = require('linkifyjs');
const linkifyHtml = require('linkify-html');

Note: When linkify-ing text that does not contain HTML, install and use the linkify-string package instead of linkify-html. Read more about Linkify's interfaces.

Usage

Example 1: Convert all links to <a> tags in the given string

const options = { defaultProtocol: 'https' };
linkifyHtml('Any links to github.com here? If not, contact test@example.com', options);

Returns the following string:

'Any links to <a href="https://github.com">github.com</a> here? If not, contact <a href="mailto:test@example.com">test@example.com</a>'

To modify the resulting links with a target attribute, class name and more, use the available options.

Example 2: Find all links in the given string

linkify.find('Any links to github.com here? If not, contact test@example.com');

Returns the following array

[
  {
    type: 'url',
    value: 'github.com',
    isLink: true,
    href: 'http://github.com',
    start: 13,
    end: 23
  },
  {
    type: 'email',
    value: 'test@example.com',
    isLink: true,
    href: 'mailto:test@example.com',
    start: 46,
    end: 62
  }
]

Example 3: Check whether a string is a valid link:

Check if as string is a valid URL or email address:

linkify.test('github.com'); // true

Check if a string is a valid email address:

linkify.test('github.com', 'email'); // false
linkify.test('noreply@github.com', 'email'); // true

Usage with React, jQuery or the browser DOM

Read the interface documentation to learn how to use linkify when working with a specific JavaScript environment such as React.

Plugins for @mentions, #hashtags and more

By default Linkify will only detect and highlight web URLs and e-mail addresses. Plugins for @mentions, #hashtags and more may be installed separately. Read the plugin documentation.
